Well then I opt to not care what he wants out of the character now.

I love his portrayal (the 1.5 movies he was allowed to actually be the character) but it is not the end all be all and there are plenty out there that can do it as well or better.
I liken it to Brosnan Bond films...Pierce is awesome and him as Bond made all of the sense in the world and he did the best he could with some really awful scripts and directions. (outside of Goldeneye which is fantastic!) The best thing that happened though was replacing him and I wouldn't really care what he has to say about the direction Bond should have gone in or should go in now.
Do I think Henry has a great Superman film in him...damned right I do. He is not the greatest actor in the world but he definitely had the chops to pull it off. If all eyes weren't on comic films because of the MCU likely they could get away with keeping him since most people wouldn't notice or care. Unfortunately Di$ney's comic film factory has made that impossible and the SnyderCutNuts have made it even worse. There is NO WAY a MOS 2 could be made without it being connected by the audience to the Snyder films. It will be hamstrung with critics and ticket buyers from the word jump no matter how much PR they do saying otherwise. The ultimate proof of this is Ben Affleck...the man spits on the street and it is somehow connected to Batman and restoring the Snyderverse.
It is obvious WB wants to shed as much of the Snyder bad juju as possible and bringing back Henry will not only prevent that but make it ten times worse.
